What is Payara and Payara Server?
Payara Server is an open source application server derived from GlassFish, with an option of 24/7 Production and Migration & Project Support. It is developed by Payara Services Ltd as a perfect solution for companies currently using GlassFish, struggling with lack of support from Oracle and infrequent, low-quality application server releases. Payara Server is also a great product for any organisation running Java EE applications, looking for a robust, secure, reliable and supported platform.
Payara Server is compatible with Eclipse MicroProfile.
What is Payara Micro?
Payara Micro is a ‘smaller’ version of Payara Server, perfect for microservices and cloud environments. It is < 70MB in size and incredibly simple to use. With its automatic and elastic clustering, Payara Micro is designed for running Java EE applications in a modern containerized/virtualized infrastructure. Payara Micro also comes with a Java API so it can be embedded and launched from your own Java applications. Find out more here.
Payara Micro is compatible with the Eclipse MicroProfile.
What is the relationship between Payara Server and GlassFish OpenSource Edition?
Payara Server is derived from the upstream GlassFish source tree with our own enhancements and fixes. Payara and Payara Server are not affiliated with, maintained, authorized, endorsed or sponsored by Oracle or any of its affiliates.
